Licensing aside, I think splitting the various functions into containers is not a good route either. This will force users to have to maintain and use containers and adds complexity to the networking aspects of ACS. Complexity decreases stability. Now I understand the argument that a monolithic approach also brings its own set of issues but it also simplifies it.

Many enterprises will not touch anything that has AGPL - the github repo shows rather infrequent updates. Quite likely they aren't considering the use cases of the CloudStack community I'd back John B's comments on disaggregating the VR. Split it into many docker containers - password server - userdata server - DHCP / DNS - s2s VPN - RA VPN - intra-VPC routing and ACL - Port forwarding + NAT - FW - LB (public) - LB (internal), - secondary storage - agent Glue them together with docker compose files (one per use case - basic zone, isolated, VPC, SSVM, etc). The VR image then becomes a JeOS + docker. You can test each of the components independently and fixing one bug in the field (say DHCP) is hitless to the other components. You don't need to build per-hypervisor VRs. You could even run on baremetal. Along the way you need to figure out how to - make the traffic traverse the containers that are needed to be traversed (in most cases just 1) - bootstrap the router (how does it find its compose file? where is the registry?) - rethink the command and control of the VR functions. SSH works, but something more declarative, idempotent should be explored. As you do this, it becomes clearer which of the functions can be substituted by for example CloudRouter. Command and Control of the docker containers can be moved out to another container. Etc. On Wed, Sep 14, 2016 at 12:59 AM, Marty Godsey <ma...@gonsource.com> wrote: > This one does look nice.
